To all 'whom t may concern.'

Be it known that JULES D. BIscAri-in'r and FERNAND CAILLETEAU, citizensof the United States, residing at Atlanta, in the county of Fulton andState of Georgia, have invented certain new and useful improvements inAttachments for Operating Snap Switches; and they do hereby declare thefollowing'to be a full, clear, and exact description of the invention,such as will enable othersskilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

rlhis invention relates to new and useful improvements in attachmentsfor operating snap switches and consists of a simple and eflicientdevice of this nature, adapted to be readily attached to the button ofthe switch and affording means whereby a spring actuated drum, operatedby a chain or cord, may cause the button to be turned. rl`he presentinvention consists of a simple and eflicient device of this naturehaving various details of construction, combinations and arrangements ofparts which will be hereinafter fully described, shown in theaccompanying drawings and then specifically defined in the appendedclaims.

The invention is illustrated in the accompanying drawings which, withthe letters of reference marked thereon, form a part of thisspecilication and in which:

Figure l is an end elevation showing the device as applied to the buttonof a switch.

Fig. 2 is a view in elevation taken in a plane at right angles to Fig.l.

Fig. 3 is a detailed view in elevation, and Fig. 4L is a centralsectional view 'through the device as applied to the button.

Reference now being had to the details of the Vdrawings by letter:

A designates a rotatable drum having intersecting transverse slots Bformed therein, provided to receive the button A. of the switch.l Saiddrum has a rib C about the same, the circumference of which rib hasratchet teeth D formed therein and said drum has an annular shoulder Eadapted to have abearing in the circular outlined opening E of the diskVF, which disk has laterally extending l. shaped lugs H projecting atpoints diametrically opposite and which are adapted to engage the slotsl formed in the disk I', which latter has a circular outfor the lined`opening through which an annular shoulder at the other end of the drumpasses and has a bearing therein. By this construction, it will be notedthat both ends ofthe drum have bearings in the disks which are parallelto each other. Said disk l has resilient arms L projecting laterallytherefrom and at points diametrically opposite and which are adapted toengage the socket of the lamp on which the device is applied purpose ofholding the disks stationary. Y i,

A ring, designated by letter N, has ,an inverted L shaped integralportion N, said ring being mounted about the drum upon which it has abearing and said inverted L shaped end has pivotally mounted therein apawl S, adapted to engage the teeth D, and a cord X is connected to oneend of said projection N and passes through the aperture in the angledend of an arm I2, which serves as a guide for the cord. A coiled spring,mounted upon the drum, intermediate the disk F and the ring N and hasone end fastened to the projection N of the ring and its other angledend J which is fastened to one of the lugs H, as shown in Fig. 4i of thedrawings.

It will be noted in Fig. 4: of the drawings, that the spring actuatedmovement of the ring in one direction is limited by one of the lugs Hwhich is disposed in the path of the projecting portion N.

In operation, when the' parts are assembled, as shown, and the deviceattached to the socket of a lamp, with the button extending through oneof the slots B,by pulling upon the cord, the ring may be given a partialrotary movement and the pawl carried by the ring will engage the teethupon the circumference of the drum and cause a similar partial rotarymovement to be imparted A to the drum, and also to the key of the snapswitch, which engages the slot of the drum. ln this movement of the drumthe spring will be under tension and when the` cord is released, thespring will return the ring to its normal starting position,carry ingwith it the pawl which is mounted thereon, the pawl turning idly overthe ratchet having circumferential teeth, disks having .circularoutlined openings in Which the ends Y of the drum are ournaled, integrallugs pro-V jecting from one disk and passing through Vapertures in theother disk and clenched ftened at one end to' said projection and itsother end to said disk.

2. An attachment for snap switches for operating thesame, comprising adrum having intersecting slots formed therein for the Yreception of abutton of a' switch, said drum having circumferential teeth, a flangeddisk 1i'z'ivii'i'g circular outlined. openings in Which ones-end of thedrum'is journaled, lugs projecting from said flange at pointsdiainetrically opposite, a second disk with circular outlined openingsin which the` other end of the drum is journaled, and provided withslots for the reception of said lugs, and iesilient arms for engagementwith the socket,

Va ring journaled upon the drum and having a lateral projection, a cordsecured thereto,

a paWl pivotally mounted upon said projection and engaging said ratchetteeth, one of said lugs being positioned in the path of said projection,a spring fastened at one end to the latter and theother end to one ofsaid disks, as set forth.
